Definitions

  • the present invention relates to a roller device for displacement of switching rails of track shifting apparatuses, commonly used in railroads.
  • track shifting apparatuses better known as AMV [track shifting apparatuses]
  • AMV track shifting apparatuses
  • an object of the present invention is to provide a roller device for displacement of switching rails which reduces from eight to one the monthly maintenance and cleaning interventions in the AMV.
  • Another object of the present invention is to provide a roller device for displacement of switching rails which does not become worn out by the friction of the switching rail against the slide chair.
  • Another object of the present invention is to provide a roller device for displacement of switching rails which is not affected by the contamination which takes place in the ballast and also in the slide chair itself.
  • Another object of the present invention is to provide a roller device for displacement of switching rails which does not require lubrication out of the business hours or working days.
  • Another object of the present invention is to provide a roller device for displacement of switching rails which eliminates the friction of the switching rails against the slide chair during the operation of the AMV so as to make it unnecessary to lubricate the slide chairs and diminish the stress of the switch machine.
  • FIG. 1 is a perspective view of a switch point of a railroad provided with the said roller device for displacement of switching rails;
  • FIG. 2 is a side view of the roller device for displacement of switching rails
  • FIG. 3 is an upper view of the roller device for displacement of switching rails
  • FIG. 4 is a longitudinal view of the roller device for displacement of switching rails, taken along the arrow “A” of the FIG. 3;
  • FIG. 5 is a sectional view of the roller which integrates the roller device for displacement of switching rails, taken along line “B—B” of FIG. 4 ;
  • the roller device for displacement of switching rails in the present invention comprises a basic structure 10 , provided in its end with a stylized horizontally-S-shaped laminar locking rib 1 , said structure 10 is centrally provided with a pair of trapezium-shaped longitudinal plates 2 parallel to each other, each of said longitudinal plates having in its mid-portion a pair of rectangular cuts 3 extending from the upper edge to half the height thereof, to which are attached the ends of the shafts 4 of corresponding rollers 5 , which have inwardly and around the respective shaft 4 a pair of bearings 6 and retainer rings 7 , allowing the rotational movement of the rollers 5 around their own axis and relatively to the said longitudinal plates 2 which support them, as shown in FIGS. 2, 3 and 5 .
  • a L-shaped laminar rib 8 which is mounted on a transversal support 11 defined by a U-shaped folded plate with horizontal extents 11 a , there being provided oblong holes lib, through which throughbolts 11 c are passed, from this transversal support 11 in relation to the sleepers D of the railroad track (see FIG. 1 ).
  • the L-shaped end 8 of the basic structure 10 is provided with a pair of through-holes 8 a , through which through-bolts 8 b are passed, which are fixed at the lower portion to the transversal support 11 , each of the said through-bolts 8 b going through and being involved by a steel spring 9 with its ends directly contacting the lower face of the L-shaped end 8 and the upper face of the mid-portion of the support 11 , exerting a separation force between the last said components, as shown is FIGS. 2 and 4.
  • the through-bolts 8 b have hexahedral heads and are prevented from turning relatively to the L-shaped end 8 and support 11 by a small horizontally-L-shaped lock 8 c , which is secured by bolts 8 d to the respective through-bolts 8 b so as to allow the vertical portion of the said locks 8 c to come in contact with one of the faces of the said through-bolts 8 b , preventing it from turning, as shown in the figures.
  • the roller device for displacement of switching rails allows the latter to move on the rollers 5 in such a way that, when the switching rail 20 is in the end of its opening course, it is placed on the rollers 5 , and when the switching rail 20 is in the end of its closing course, it is about to move upward upon the rollers 5 , thus being ready to start an opening displacement.
  • the springs 9 at the beginning of the movement of the switching rail 20 , are compressed in order to allow the said switching rail 20 to have an easy access to the rollers 5 with no need of any additional stress from the switch machine.
  • the rollers 5 used in the device for displacement of switching rails can be fixed or detachable, and the damping system can comprise springs 9 or rubber.
